Presentation
Urine retention and dysuria
Patient Data
Mild bilateral pelvicalyceal ectasia is noted.
Multiple echogenic shadowing urinary bladder stones are noted with various sizes ranging from 1.7 - 2.3 cm.
The prostate is seen enlarged averaging 81 cm3 in volume.
Thick bladder walls were noted averaging 6 mm in thickness.
Pre-voiding bladder volume= 431 cm3
Post-voiding bladder volume = 422 cm3
Case Discussion
Urinary bladder stones are fairly uncommon in normal bladders.
Patients with urinary stasis are at increased risk of bladder stones formation.
This patient had a history of benign prostatic hyperplasia on treatment for 10 years.
This prostatic enlargement was probably the main cause for his chronic outlet obstruction aiding to the urinary stasis, evident on the pre and post voiding bladder volumes.
